MRK-IDIX deal dispels two longstanding biotech canards: Canard #1 Big Pharma won’t pay a large premium to the market price of a small or medium-sized biotech company. Fact: MRK is paying a 239% premium to IDIX’s closing price on Friday (i.e. the buyout price is 339% of Friday’s close). Canard #2 News of a biotech buyout always leaks. Fact: There was no leakage in this case.
